Chapter 10 - Bonding Theories

What is the hybridization and the shape around the central atom of the following molecules?

NH₄⁺, BeF₂, CH₃⁺, PCl₆^-, XeF₂

See Solutions

Solution

NH₄⁺ ⇒ 4 electron groups around N (4 atoms) ⇒ sp³ ⇒ tetrahedral

BeF₂ ⇒ 2 electron groups around Be (2 atoms) ⇒ sp ⇒ linear

CH₃⁺ ⇒ 3 electron groups around C (3 atoms) ⇒ sp² ⇒ trigonal planar

PCl₆^- ⇒ 6 electron groups around P (6 atoms) ⇒ sp³d² ⇒ octahedral

XeF₂⇒ 5 electron groups around Xe (2 atoms + 3 lone pairs) ⇒ sp³d ⇒ trigonal bipyramidal
